TY - THES A1 - Pingel, Ruta T1 - Well-being effects of proactivity through the lens of self-determination theory N2 - In modern times of evolving globalization and continuous technological developments, organizations are required to respond to ever-changing demands. Therefore, to be successful in today’s highly uncertain environments, organizations need employees to actively search for opportunities, anticipate challenges, and act ahead. In other words, employee proactivity in the workplace represents a highly valuable resource in nowadays organizations. Empirical studies conducted as part of this thesis advance the research on the outcomes of proactivity from the individual perspective. The main contribution of this thesis pertains to revealing several important individual and contextual conditions under which engaging in proactivity will have negative and positive effects on employees’ well-being and their consequent behaviours, as well as shedding light on the unique psychological mechanisms through which these effects unfold. From a practical standpoint, this research underscores the importance of creating work environments that support employees’ autonomous motivation for proactivity and urge organizations and managers to be mindful about the pressures they place on employees to be proactive at work. Besides, this thesis stimulates research efforts aimed at further extending our knowledge of when and how individual proactive behaviours at work will do more good than harm for those who enact them.

The psychometric properties and construct validity of the measure were tested in two samples of children in middle childhood (N = 1069–1657) and middle childhood to adolescence (N = 1533). Both the teacher and parent rating scale showed good item characteristics. Results of confirmatory factor analyses supported their hypothesized factorial structure. The agreement of teacher and parent ratings was satisfactory. Evidence on the construct validity of the scale was further derived from a nomological network comprising control cognitions, motivational orientations, and cognitive ability. The measures proved to be invariant across school years and raters. We discuss several avenues for future research on personal initiative in the fields of development and education.
